- The object of this invention is to obtain av simple and efficient means for discharging ashes and other refuse matter from steam-vessels, whereby the' labor of elevating and discharging the sameoverboard, as now practiced, will be avoided. f

. vThe invention consists in the employment oruseof a receiver providedwith a valve so'v arranged as to admit of a comm unioation being form/ed between the receiver and the water at the exterior of the vessel, and to admit of said communication being cut od when de sired, a pump or steam-pressure, either Or both, being used in connection with the rcceiver, and all arranged in such a manner as to effect the desired end.

: To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a receiver, which may bev of inverted ,conical `lform `placed in the lower part-of'a vessel at the place most convenient to the ashes' or other matter to be discharged. Thisreceiver is attached at its lower end to a tube, I B, which extends through the bottom or lower part of 4the side G of -the vessel, and within this-tube B there is iitted a slide-valve, D,:by which a communication maybe formed between the receiver A and the water` at the .exterior of thevessel, and said communication cut off when necessary. E 'is al force-pump, the suction-pipe F of fwh'chgtopglnuiunicates with the lower part-of'.

une receiver A. .The force or eduction pipe Gr communicates with the tube B below the valve D, as shown clearly in Fig. 1.

The operation when the pump is used is as follows: The reservoir A is lled with ashes, thevalve D being closed, and the ashes put into the receiver through an opening, a, in its top. This opening a, when the receiver is iilled, is closed by a plate, H, arranged andv packed Similar to the man-hole plate of a steain'boiler. The valve D is then opened and lwater from the exterior of the vessel rushes into the receiver A. The heavier portions of the contents of the receiverwill drop out by virtue of their own gravity, While,

owing to the motion of the vessel, nearly all the light matter held in- .suspension will be washed out. The valve D is' then closed.,and the pump-E put in operation, the water being drawn from the receiver and forced out through the tube B. A cock, I, isv inserted in the upper part of the receiver to admit air duringl the pumping operation. This pump arrange-y ment is applicable to steam-vessels using surface condensers, where steam could not be readily, spared to force the Water from the receiver. When the jet-condenser is employed and blow-valves frequently used, steam-pressure may be employed for that purpose, as follows J is a pipe communicating with the upper f part of the receiver A and leading from the steam-boiler, and provided with a stop-valve.

B is a pipe connected with bottom blow-pipe of boiler, also provided with a stop-valve.

' After the receiverAis filled and thevalve D opened steam is shortly .tlter admitted into the receiver through the pipe J, .which forces the contents of the receiver out through' the tube B. The 'valve D is closedwhile Athe steam is still entering A.. 1f the water entering the receiver is cold enough to condense any amount of steam, the bottom blow through.

pipe K can first be used, which may be done in most cases without vany bad effect to the boilers. By this meansthe'rccciver will be lledwith hot water, which may be ejected by steam pressure without any diiliculty whatever. v

Having thus described our invention, what We claim :1s new,'z\nd desire to secure by Letters Patent, is-

Ejectug or discharging; as'iles and other rufuse matter 'mm stamm-vessels bj means o' ranged as to be capable 'of being' used in councctiou with pressure exered by a, pump,

i a receiver provided with a valve, and so ar l Steam, or other suitable agency, as herein set forth.
